A few of "unable to load sound fx"

[Dehela]

I have spotted a few instances of sound effects not being loaded (according to log output). You get those during loading of some save file or starting a new game.

unable to load sound fx: ENV_NIGHT_TONSOFINSECTS
unable to load sound fx: OW_BIRD11

Also getting this after first opening video, though to be fair it is indeed missing in most of game versions (checking steam depots, I can see it only in German and Polish versions) and not OpenGothic fault, just listing for the sake of completeness:

unable to play video: "Addon_Title.BIK"

Update: A few more but didn't pay attention when. Probably that's enough, going to skip if I get more.

unable to load sound fx: SWIMWAVES
unable to load sound fx: PICKLOCK_UNLOCK
